Eeeek! Is this guy crazy? It would have to be stuck in carbon-loaded foam, and kept in a Faraday-cage container (metallized stat bags, or similar). IR would be the LEAST or your worries. Now if you're a follower of Erich von Dainken, :-) you could inscribe your source in Gold leaves, as certain pre-pre-columbian 'civilizations' supposedly have done. Your assembly code will then be forever immortalized for future generations to puzzle over. Who knows? It may even become an object of worship . . . . <Tongue now removed from cheek> Jeff +------------------------------------------------------------------+ |Disclaimer: | | | | These opinions are entirely my own, and in no way reflect the | | policies or opinions of my employer. | | | +------------------------------------------------------------------+
